Scope level?

04-18-2019, 22:23

For a long time I've been looking at scope mounted rifle leveling devices. I've been of the opinion that controlling cant from shot to shot should make a big difference in long range accuracy. They always seemed relatively expensive for the materials involved. Lately I've seen some on E-bay that are relatively inexpensive so I thought what the heck, I'll try them.

I bought a pair of these in the swing over style to check the level of my rifle for long range P. Dog shooting. They are pretty well built for about $6.50 each. They fit either 1" or 30mm scope tubes using plastic insert bushings for the 1" tubes. Only downfall is that they are about .625 from front to back. Because of the way they are put together you need almost 1 1/2" of clearance between the scope mount and the scope bell or the scope mount and the scope turret to have room to put it on the scope. You have to slide the hinged halves apart to get them around the scope tubes. Either that, or you need to put it on the tube before you mount the scope.

Mounted on a 1" scope with standard turrets you can actually mount it in front of the turret and see the bubble over the top of the turret with the level in the closed position closed. It just takes an upward glance. With Target turrets you need to flip the bubble chamber open to the view from the side of the scope. For me it seemed to work better when I looked at it with my scope aiming eye. Bear in mind that I have not had it to the range yet.

Has anyone tried a similar device with any gain in accuracy?

I've tried the cheap amazon ones and have had bubble insert, either not level or fall out, under recoil.

I use the https://www.swfa.com/swfa-ss-tac-30m...1-inserts.html on several rifles. Vortex one looks similar. I mount mine behind front ring and on left side, you look past side turret, with your off eye, to view it, so you don't lose position to use it. I wouldn't bother mounting one on hunting rifle, but on bench guns, they're very useful.

I set rifle's scope first (verified by shooting the box) and then add level to it.

Columbia Falls, MTIf we don’t speak out against the infringements of today, it will weaken our ability to stop the next infringements.

Since it took 26th Amendment to change voting age, expanding rights under 14th Amendment. Why doesn't same requirement, to restrict rights, extend to 2nd Amendment?

I have a couple of the Vortex ones. They work okay, but I don't like having to look to the side to see what is going on. I have grown fond of the levels that are built in to the rear of the MPA chassis, and Spuhr mounts. Either option is a bunch of coin, but it is a world of difference being able to see where you are with your shooting eye.

seems to me the cant is small, and when you remove your head to see the bubble, then return to x-hair you lost any level. seems to work it needs to be in the scope, on the sight picture.

Agree for those top mounted bubbles. But with a side mount (like the Vortex or the bronze colored one in post #1.) there's no need to lift the head, just open the closed eye (if that's how you use a scope. Well, I do anyhow.)

Use scope levels on my long range target rifles mainly for setting up the rifle on the rest. Once the shooting starts I will glance at it every now and then, just confirm my rifle is tracking on the bags. When competing I am a runner not a picker. In a hunting situation my pea brain has all it can handle with out checking a scope level. I do level my cross hairs with a plumb bob at the range.
